In a good economy and in a bad economy people seldom think about all the jobs that do exist. If you are in a restaurant and asked to name some jobs around town, you probably would say the waiters, cooks, and janitors. Those jobs can be seen right inside the restaurant and so they are known about.
But wait until you go to grab a straw and some napkins , do you think about jobs then? No. Yet a truck driver has a job to bring those straws and napkins to the restaurant. Also if a oven or refrigerator breaks, a repair man is called to fix it and his job also exists.
In Capitalism there is the
seen and
unseen. In the restaurant the customers benefit from customer service that can be seen as well as deliveries made to the restaurant that the customer doesn't see.
And the beauty of Capitalism is that all those things happen without a single person or politician knowing how to make a perfect restaurant . Because under Capitalism the truck driver wants money so he delivers utensils to the restaurant, the server needs money so he goes to work there, and the janitor wants to make money so he shows up to clean the place.
In their quest for capital (money) they all make the restaurant run smoothly with no instruction from a Government bureaucrat. Think about that, it's fun learning Capitalism.
